Hi,

This patchset contains a new Linux* Kernel Driver for Intel® VPUs.

VPU stands for Versatile Processing Unit and it is an AI inference accelerator
integrated with Intel non-server CPUs starting from 14th generation.
VPU enables efficient execution of Deep Learning applications
like object detection, classification etc.

Driver is part of gpu/drm subsystem because VPU is similar in operation to
an integrated GPU. Reusing drm driver init, ioctl handling, gem and prime
helpers and drm_mm allows to minimize code duplication in the kernel.

The whole driver is licensed under GPL-2.0-only except for two headers imported
from the firmware that are MIT licensed.

User mode driver stack consists of Level Zero API driver and OpenVINO plugin.
Both should be open-sourced by the end of Q4.
The firmware for the VPU will be distributed as a closed source binary.

I'm resending v3 patchset with correct Dave's email.

Regards,
Jacek

v3:
- Fixed alignment warning in ivpu_ipc.c when building with W=1

v2: https://lore.kernel.org/all/20220913121017.993825-1-jacek.lawrynowicz@linux.intel.com/
- Rename the driver from "drm/vpu" to "drm/ivpu"
- Add a TODO file
- Add support for WC buffers

v1: https://lore.kernel.org/all/20220728131709.1087188-1-jacek.lawrynowicz@linux.intel.com/

Jacek Lawrynowicz (7):
  drm/ivpu: Introduce a new DRM driver for Intel VPU
  drm/ivpu: Add Intel VPU MMU support
  drm/ivpu: Add GEM buffer object management
  drm/ivpu: Add IPC driver and JSM messages
  drm/ivpu: Implement firmware parsing and booting
  drm/ivpu: Add command buffer submission logic
  drm/ivpu: Add PM support

You have to add yourself to MAINTAINERS.

I assume that there's a FOSS userspace available?

Rereading the cover letter, it will be opensourced. I think DRM policy 
is that we first need an OSS userspace befor the kernel driver get's 
merged. Nevertheless it's now a good time to get the driver in shape.

I've finished looking trough the patchset and left comments on some of them.
